Thanks Rick and James, and yes that was a rivet of some form in the back of the bar, which was loose, and it now hides somewhere in the carpet (as of about 2 minutes ago), I will have to do a search and locate the little beast, but it wasn't attached to anything, and when I gave it a gentle touch with a finger nail it bailed out straight into hiding somewhere in the carpet. (I am doing some 12 hour day shifts at the moment, and have only just arrived home, so will get some time to scratch around for it when I get some more time. Your comments are greatly appreciated, and thanks agan. Best wishes Bob
